POS'T-EXTRACTOR.

SPECIFICATION forming part of Letters Patent No. aveeoauatea January 24,1898. Application filed August 25, 185 Renewed June ll, 1837. Serial No. 2-ll,026. (No model.) I

Be it known that I, WILLIAM R. ,OYLER, a citizen of the United States, residing at Topeka, in the county of Shawnee and Stateof Kansas, have invented certain new and useful Improvements in. Post-Lifters, of which the following is a specification, reference being hadtherein to the accompanying drawings.

Figure l is a perspective of the device ready to be operated. Fig. 21's a side elevation -of the lever. Fig. 3is a top plan of the block. Fig. 4 is an edge view of the toothed part of Fig. 5 is a front elevation of the This device belongs to that class called postlifters or stump-extractors, and the novelty consists in'the construction and combination of the several parts-namely, the baseblock and the'indepeudent and detachable le-' ver and toothed blade, whereby the said lever is fulcrumed on the block and the blade operated in said slot, so as to havean upward lifting force on the post -or' other thing to be lifted, all as will now be more fully set out and explained, reference being had to the accom panying drawings.

- In the drawings, A denotes the fulcrum block or base,which may be made of wood and in several pieces or of metal cast in one piece. If made of wood, I prefer to have the grain of the bottom piece ,at right angles to that of the upper piece. In the front part is axvertical and somewhat-tapering slot, at, about three-fourths of an inch wide and extending back a third (more or less) of the length of the block. The upper ends of thesides a,"forming this slot, are beveled at a I I Integral with the block or securely fastened on each side of the slot a, on the tops of the side a, are the crotches B, one on each side, made generally in the form of an inverted W; Thefront ends of this, whenthe block A is made of wood, fit snugly on its beveled ends a"; but when the block is cast these crotches 'will be an integral part thereof.. In the rounded parts b 0f the crotches the-rounded, ends 0 of the split lever Crest, and are capable of being freely moved thereon. The blade D of thelever, which is rigidly secured at one end between the split ends c of the lever, is

adapted in shape and size to move freely be- I tween the crotches and inltheslot in the block A. The front or edge part of the lever. blade is-curved, so that in operationit shall d, generally V-shaped. I As thus made it will be observed that the lever and blade practically form one piece, and are readily detachable from the base-block when necessary; but, I

if desired, the lever could be permanently secured to and upon the block. When the blade is in position for use, the points of theseteeth extend upwardly and somewhat outwardly; The teeth are also staggered. Thus saidteeth will hold to a wide surface when fixed in a railroad-tie, post, or other object being lifted,

so that, if, the wood .of the said tie or other article is not wholly firm,- as by rot or other-f bemade railroad-tie, or other object .to be lifted,- said ironcrotches or bearings thereon being up. I Then I place said lever with said blade curved and so made an eccentric, and toothed, as aforesaid, in the said rounded crotches or bear ings onsaid fulcrumablock. Then I bear down on said lever by the handle thereof. 1 Said teeth engage with and sink into considerable width of the post, tie, or other-object to be raised.

toothed semicircle of irondoes not let go, being an eccentric, and pressing more and more against. it as it is raised; nor does it let go because the wood may be decayed, said teeth ject on different lines.

Having thus described I consider new, and desire-to secure byLetters Patent, is-'- 1. Apost-lifter or similar device consisting rot of a base or fulcrum block vertically'slotted in front and having crutches orlever-seats 0n act as an eccentric, and provided with teeth I wise, the edge ofthe blade will yet be able to or partially de- 7 To operate'said machine, Iplace the'slotted, end of said fulcrum-block against the post, So

As a post is raised andbecomes'loose, said'go being staggered and engaging with such 0b- 5' my inventiomwhatI i I each side of said slot, combined with a lever having at its lower end a blade fitting into said slot and having staggered teeth, substantially as described.

2. The fulcrum-block slotted in front and having the crotches at the top and on each side of the-said slot, combined with the'lever having rounded ends to rest on the said crotches and the blade provided with staggered teeth on its curved front edge, substantially as described.

3. lhe combination of the block A, slotted vertically in front at a and having crotches B,
